If one server binds to INADDR_ANY with port N, then any other socket
can be bound to a specific IP address with port N. When packets
come in destined for port N, the delivery will be prioritized
to whichever socket has the more specific and matching binding.
So the kernel is fine.
Netperf just needs to be more careful in order to handle this kind of
case more cleanly.
